Hi WolfSoul - I agree with pparks too but for slightly different reasons (though his reasoning is valid as well). I used 10,000 rpm raptors in Raid 0 very heavily every day for 3 years and never had any disk problems (so I was lucky) and I did appreciate the speed bump and the increased volume size - BUT, BUT - the OCZ's don't have "Garbage Collection", they use TRIM support and Wear Leveling to prevent SSD performance degradation.
And Windows 7 DOES support the SSD TRIM command - BUT, BUT - the TRIM wont work (at this time) if the drives are setup in a RAID configuration. Someday they'll get TRIM to work in a RAID system but it hasnt happened yet.
I think you're better off with using the second SSD as a "second system drive" for your games. I have two SSD's and thats what I've done. I also moved the majority of my page file to the second SSD. I have 12 GB of ram and I'm one of those folks that harbors the notion that the page file should be equal in size to the installed ram - so I moved 11 GB of the page file to the second SSD and only keep 1 GB of it on the OS boot SSD. I've tried to setup the OS SSD so that it gets written to as little as possible and I've tried to keep the amount of used space on it to a minimum. All I keep on the primary SSD is the OS and my system programs.
I don't want to see degradation in either SSD but keeping the OS SSD as fast as possible (over the long haul) is my primary goal. So far it's been working pretty well - I use my rig for maybe 8 hours a day and so far (after 7 months) my SSD's read and write speeds haven't deteriorated at all.
This is just what I do personally, we all do our own thing, don't we ...... Cheers
